If you want to increase your odds of having a long and lively lifetime, scientists say, work on getting an average of seven or eight hours of sleep a night. If you get only six hours or less, you stand a 70 percent chance of dying before your time.
Scientists are finding that if you don’ t get enough sleep, you are putting yourself at increased risk of heart trouble, digestive disease, or a serious, even fatal (致命的) accident. When tired, your sight, hearing, and attention are slow to alert you to dangers--and once you are aware of them, your reactions are also slow.
H. Craig Heller--a professor of biology at Stanford University--is one of a small army of scientists studying the reasons why many people can’ t sleep and wake refreshed, why the brain puts you to sleep, and why lack of sleep causes such powerful effects.
Heller notes that most major accidents have occurred in the early morning, when workers probably were still sleepy from deficient (不足的) sleep. He includes the explosion at the nuclear power plant at Chernobyl in Ukraine, the release of poisonous gas at Bhopal, India and the nuclear accident at Three Mile Island in Pennsylvania.
Scientists estimate that more than 100 million Americans have sleep troubles of some kind. Getting too little sleep heads the list. As many as one American in five gets fewer than six hours of sleep a night. Some people can get along on six hours, but most of us need between seven and eight--and children and young adults need up to 10 hours. As we age, it becomes more difficult to get enough sleep. At any age, however, we all can pile up a sleep deficit that eventual ly will force us to fall asleep-whether we’ re ready or not. [br] It can be inferred from the passage that ______.
选项
A、people of an older age are more likely to suffer from deficient sleep
B、the older one becomes, the more sleep he or she will need every night
C、everyone of us needs to have seven or eight hours of sleep every night
D、even if we are tired, we can still react quickly as soon as we find dangers
答案
A
解析
推断题。根据最后一段第五句As we age,it becomes more difficult to get enough sleep可推断选项A为正确答案。
